Forrest, Thurlaston, Leicestershire, England Filed June 27, 1966, Ser. No. 560,500 Claims priority, application Great Britain, July 1, 1965, 28,006/ 65 3 Claims. (Cl. 229-14) This invention relates to packaging containers and is an improvement in or modification of the invention claimed in Letters Patent No. 3,132,789.

Letters Patent No. 3,132,789 claims a packaging container comprising an inner receptacle consisting of a closed bag or envelope of a flexible sheet material with a filling and dispensing device secured to a wall thereof, and a rigid or relatively rigid outer carton comprising four side wall panels which, when erected, form a housing of rectangular cross-section intimately enclosing said receptacle, the receptacle and carton being collapsible into a flat laminate by folding at the corners of the erected carton, and side walls of the carton and receptacle which stand face to face in the erected container being attached to one another so that erection of the carton automatically erects the receptacle.

In a specific form described in the aforesaid Letters Patent the inner closed bag or envelope, as seen collapsed, is of hexagonal outline shape, and the object of the present invention is an arrangement which will simplify the bag manufacture.

Thus, in the container of this present invention the inner closed bag or envelope is of rectangular, or substantially rectangular, outline shape in its flattened condition, and is secured in the outer carton with one pair of opposite corners projecting beyond the upper and lower edges of the side walls of the carton and with the other pair of opposite corners folded back to lie between the carton and the main body of the bag or envelope.

In a very simple version the inner bag or envelope is of square outline in its flattened condition and its side edges are disposed at 45 to the side edges of the carton.

One form of packaging container made according to this invention is illustrated in the accompanying drawings wherein:

Both FIGURES 1 and 2 show the container in the collapsed condition with the inner bag assembled in the outer carton. In FIGURE 1 the outer carton has been opened out on one side to show the construction.

Referring to the drawing, the bag 1, When flattened out, is square and comprises a back panel and a front panel made of polyethylene or other suitable film material, the said panels being joined together along their marginal edges by heat sealing. One of the panels of the bag 1 is vided with a cap 2.

The outer carton is made of cardboard or sandwich corrugated material with fold lines defining four wall panels 3 each with a bottom flap 4 and a top flap 5.

In order to assemble the container, adhesive is applied to the carton panels 3, preferably to the marginal areas around these panels, leaving a narrow, unlocated strip adjacent each side edge of each panel. The square, flat, and peripherally-closed inner bag is then arranged centrally on the opened outer carton blank and orientated at 45 to the latter so that two opposite outer corner portions 6 thereof overlap and project beyond the outer edges of the flaps i and 5, whilst the two other corner portions 7 of the bag project beyond the respective inner carton panels 3 and lie on the two outer carton panels. The nozzle is so arranged as to pass through an aperture provided in one of the outer panels 5.

In order to complete the container the free edges of the outer carton panels 3 are brought together and connected, for example by adhesive tape. It will be noted that the corner portions 7 are folded in with the outer panels 3.

In order to erect the container, it is only necessary to press the two outer edges of the flattened pack together, and the erection of the outer carton will be accompanied by a like erection of the inner bag. At the same time the corners 6 will collapse down, as described in Letters Patent No. 3,132,789. The corners 7 are already tucked flat between the side walls of the bag and carton and play no part in the erection or collapse of the container.

I claim:

1. A packaging container comprising an inner closed bag or envelope, of a flexible sheet material, which collapsed flat is of rectangular or substantially rectangular outline, an outer carton comprising four hingedly-connected side Wall panels, and a filling and dispensing spout secured to said bag or envelope and accessible through said carton in the erected and closed container, said bag or envelope being assembled in said carton with one pair of opposite corners of the bag or envelope projecting beyond the upper and lower edges of the carton side wall panels, and with the remainder of the bag or envelope overlying the whole, or substantially the Whole, area of the adjacent side wall panels and secured by adhesive to latter so as to move in unison with the respective side walls during erection or collapse of the container.

2. A packaging container as claimed in claim 1, in which the carton side wall panels are each provided with an upper and a lower hinged closure flap, the filling and dispensing device being secured to one of these, and the aforesaid projecting corners of the bag or envelope projecting also beyond these flaps in the flattened container.

3. A packaging container as claimed in claim 1, in which the inner bag or envelope is of square outline in its flattened condition and its side edges are disposed at 45 to the sides edges of the carton.
